I have been standing motionless in front of the mirror for several hours now. I am inspecting my eyes, neck, waist, and legs. I no longer see myself, a smiling 15-year-old girl. My perspective is obscured by all the faults I see in me. I nervously tap my foot while I compare my appearance with the looks of models, whose Instagram photos I like every day. Why do not I have their sparkling smiles, long shiny hair, and narrow waists? Why am I not as perfect as they are? And what does it mean to be beautiful in the modern age?
